[b2g] How to mount yaffs on NAND

[Jose Vidal]

Hi everyone,
 
I have a iMX6Q processor whit NAND flash.
The NAND uses ubifs like file system.
 
According the source code, I have two methods to mount a system.img
 
Used for NAND: device/fsl/imx6/etc/fstab_nand.freescale
--
ubi0:system /system ubifs   ro  
wait
ubi0:data   /data   ubifs   nosuid,nodev,nodiratime,noatime 
wait
ubi0:cache  /cache  ubifs   nosuid,nodev
wait
ubi0:device /device ubifs   nosuid,nodev 
wait
 
 
Used for SD-card: device/fsl/imx6/etc/fstab.freescale
---
/dev/block/mmcblk0p5/system  ext4ro 
  wait
/dev/block/mmcblk0p4/dataext4
nosuid,nodev,nodiratime,noatime,nomblk_io_submit,noauto_da_alloc,errors=panic   
 wait,encryptable=footer
/dev/block/mmcblk0p6/cache   ext4nosuid,nodev,nomblk_io_submit  
wait
/dev/block/mmcblk0p7/device  ext4ro,nosuid,nodev
 
 
 
The build process creates the system.img file with yaffs like file system.
 
How I make to mount the system.img file to mount point. I mean, to  "/system" ?
 


I hope for your help.
 
Thanks in advance.
 
Best regards.

Re: [b2g] question regarding realtime performance guarantees

[Dave Hylands]

Since Android and FxOS are both based on linux, and linux can't guarantee 
realtime performance, neither can guarantee realtime performance.

Both Android and FxOS use garbage collected languages (Java for Android, 
JavaScript for FxOS) which don't use realtime garbage collectors, so even if 
the OS were realtime, it still wouldn't help unless the portions of interest 
were written in languages which don't need GC (like C or C++).

YES! :D

Is this just one single app, which implements mesh networking for its
own services?

If we want to support mesh networking, we might want to look for
something more general. An option would be the BATMAN protocol and tools
[1]. It operates on OSI layers 2 and 3 and is supported by Linux kernel
natively.

[Kai-Zhen Li]

Hi Jose,

I think you will need to build system.img, userdata.img in ubifs format.
This is for you reference:
1. patch platform/build and 
2. add the related flags in device config
3. mkfs.ubifs (out/host/linux-x86/bin/mkfs.ubifs)

How to patch platform/build,

Re: [b2g] How to mount yaffs on NAND

[Thomas Zimmermann]

Hi Jose,

You can set

  TARGET_USERIMAGES_USE_EXT4 := true

in the file

  device//BoardConfig.mk

to create ext4-based images. If you have eMMC-based storage, you also
need to run 'rmt_storage' on the device AFAIK.

Best regards
Thomas

Re: [b2g] How to mount yaffs on NAND

[Jose Vidal]

Hi Thomas,

Thanks,

I think that ext4 file system is used only with sd-card.
Or maybe I'm confused.

My target is to use the NAND Flash memory.

What do you think ?

Best regards.

Re: [b2g] How to mount yaffs on NAND

[Jose Vidal]

Hi Kai,

I have two questions:

1. What is the platform_build version which you have patched?
2. When you say: add the related flags in device config, you mean to

$ ./build.sh BUILD_TARGET_FS=ubifs

The BUILD_TARGET_FS variable works with the imx6_target_fs.mk file

--imx6_target_fs.mk--

ifeq ($(BUILD_TARGET_FS),ubifs)
# build ubifs for nand devices
TARGET_USERIMAGES_USE_UBIFS := true
TARGET_USERIMAGES_USE_EXT4 := false
PRODUCT_COPY_FILES += \
device/fsl/imx6/etc/fstab_nand.freescale:root/fstab.freescale
else
# build for ext4
TARGET_USERIMAGES_USE_EXT4 := true
TARGET_USERIMAGES_USE_UBIFS := false
PRODUCT_COPY_FILES += \
device/fsl/imx6/etc/fstab.freescale:root/fstab.freescale
endif # BUILD_TARGET_FS

-


I have out/host/linux-x86/bin/mkfs.ubifs.

Thanks in advance.

Hi Joes,

1. I patched to branch b2g-4.4.2_r1 of 
git://github.com/mozilla-b2g/platform_build
2. Yes, need to make sure ubifs is trigger during build.

Re: [b2g] How to mount yaffs on NAND

Hi Kai,

After the patch, I get the next error during the build:

===

What do you think is the problem ?

I think that Gareth was saying that these informations needs to be in
the bug's description. He was not saying it's a condition to open the
bug in the first place.

Re: [b2g] Making User Stories Obvious in Bugzilla

[Julien Wajsberg]

Hey Gareth,

While I understand this whole mail was meant to enforce good practices
(and that's good!), I think it went out quite wrong and agressive, and
that's quite unnecessary.

Don't forget we have people from different languages and cultures in
this project, and sometimes misunderstandings can happen.

Keep the good work!

This is exactly what I had in mind. Possible approaches might be:
1. Allow some apps to be written at a lower level and not use dynamic
memory management and GC
2. Handle telephony operations by an interrupt, so that calling/texting
always overrides the rest of the app framework
I think we'll build a better mobile OS this way. My humble opinion only.

Re: [b2g] Flash without debug flag

[Armen Zambrano G.]

I was lucky that after rebooting I receive a new update.

I'm nevertheless trying to flash the device and I can't see it listed
under adb devices even after enabling:
* "Settings->Developer-> Remote debugging dropdown and check "ADB and
devtools"

I also added this:
SUBSYSTEM=="usb", ATTR{idVendor}=="05c6", MODE="0666", GROUP="plugdev"
to /etc/udev/rules.d/51-android.rules

Armen

[b2g] Flash without debug flag

[Armen Zambrano G.]

Hello,
I'm trying to flash my Keon device, however, last week the Settings app
broke and I did not have the remote debug flag on at that moment.

As part of the flashing process I need to have that flag on [1]
How can I fix the device?

For the record, updates stopped working so I can't get back into good shape.

cheers,
Armen

Re: [b2g] question regarding realtime performance guarantees

[Thomas Zimmermann]

Hi,

Just out of interest, is there any actual use case here?

>From a technical POV, phones are short on resources and the software is
mostly driven by user input. RT, in contrast, is often bad for resource
usage and interactive workloads, because you have to expect WCET for
many components. So you have to allocate resources for RT tasks,
although you probably won't actually need them. In the end you'll
achieve the opposite of what you intended.

And please note that telephony runs on a separate CPU, which comes with
an RT-enabled OS.

Best regards
Thomas

Re: [b2g] Flash without debug flag

[Andreas Pehrson]

Hold volume up as you boot and it should boot into recovery mode.

Adb is enabled in recovery on the keon, so you should be able to run
flash.sh there.
If not, reboot into fastboot mode manually (adb reboot bootloader) and then
run flash.sh.

If you only want to flash gecko or gaia, I am not sure if that works in
recovery - if /system is mounted or not. A full flash should work though.

Mainly, my question is about 

===

init: command 'chmod' r=-30
init: command 'chmod' r=-2
init: command 'chmod' r=-30

===

This is caused by

# mount ubifs partitions
mount_all /fstab.freescale
chmod 0755 /system/b2g/b2g
chmod 0755 /system/b2g/updater
chmod 0755 /system/b2g/plugin-container



Why I have these error messages?


I hope for your help.


Thanks in advance

[b2g] b2g is not running during init process

[Jose Vidal]

Hi everyone,

I'm porting B2G on freescale device.

I stopped the /system/bin/b2g.sh process during init. This process is running 
in infinite loop.

When I try run the b2g.sh manually, I have the next error message:



root@android:/ # ./system/bin/b2g.sh   
soinfo_link_image(linker.cpp:1635): could not load library 
"libhardware_legacy.so" needed by "/system/b2g/b2g"; caused by

I checked the libhardware_legacy.so lib inside the /system/lib

-rwxrwxr-x system   system  21764 2014-03-28 12:36 libhardware_legacy.so

Any idea which one is the problem?

I hope for your help,

Thanks in advance.

[b2g] unlock screen in B2G Desktop

[Saulo]

Hi,

   I am trying to build B2G for my desktop following the instruction described 
here: 
https://developer.mozilla.org/en-US/Firefox_OS/Using_the_B2G_desktop_client but 
after the build when I execute b2g it is showing a locked screen where I am not 
able to unlock using the mouse cursor.

  So described in the Mozilla's tutorial the topic "Creating a 
custom-settings.json" tells me how to fix it creating a file called 
custom-settings.json and setting "lockscreen.enabled" and "lockscreen.locked" 
to false.

  But Gaia source code already have a file called "common-settings.json" with 
"lockscreen.enabled" and "lockscreen.locked" option so I am not sure if it is 
really necessary to create a new file called custom-settings... and even when 
using lockscreen as false it is showing a locked screen.

  Is someone building Gaia for desktop here? How can I solve this problem?

thx

Probably one of the libraries that libhardware_legacy.so needs is missing.

On your host machine you can go do:

cd out/target/product/DEVICE-NAME/system/lib
readelf -d libhardware_legacy.so

and it will print out what libraries are needed to load libhardware_legacy.so

Repeat readelf for each of the libraries to find out what libraries they need 
etc. Verify that ALL of the needed libraries are in your /system/lib

[b2g] Installing Marionette on production builds

[Malini Das]

If you happen to have a production build and need to use Marionette 
against it (say you want to run gaia integration tests or gaia-ui-tests, 
etc.), you can now install Marionette as an extension:


https://github.com/mozilla-b2g/marionette-extension

This only works for 1.3 builds currently. I'll have to add 1.4 support 
soon. If you need any extra features/support, file github issues, thanks.

[b2g] Introducing Mulet

[Jonas Sicking]

Mulet, french, noun. Half horse, half donkey.
Mullet, english, noun. Business in the front, party in the back.

Alexandre Poirot and Alexandre Lissy have been working hard on a new
development environment that should be a big improvement over both
what we use internally for Gaia development, and what we are asking
3rd party app developers to use when developing apps for FirefoxOS.

The basic idea behind this environment is to take Firefox Desktop as
it exists today (including its support for both internal and external
dev tools) and then run it using the same Gecko that we use for
FirefoxOS. So the backend half is FirefoxOS, the frontend part is
Firefox desktop.

This means that we'll have the exact same great development experience
that we have for Firefox desktop today, but we can use the real
implementation of various FirefoxOS specific APIs that we use on
devices.

One nice example of this is that we can keep the app: protocol working
in Mulet. So we don't need to rely on running a local http server and
run gaia through special http urls. Ultimately the goal is to enable
the app: protocol in Mulet to either load from a compressed zip file,
or directly from your gaia source tree.

Once Mulet is ready, it will *replace* the following development environments:
* B2G Desktop
* Gaia-on-Firefox-desktop
* Simulator

So it will be one tool that is usable for gaia developers, gecko
developers and 3rd party app developers.

The name "simulator" might still be around since it's something that
we've been evangelizing to developers a lot. But it will eventually be
based on Mulet.

The goal is to make this tool have nightly releases which works just
like firefox desktop. Or you will be able to build it yourself if you
need to depend on tip. This will require the help of the releng team
though.

Making all of this play well together is a lot of work. So any help
you can provide to Alexandre and Alexandre is very appreciated. We
want this environment to fit your needs, so we can build in whatever
features or tools that will make development better for you. But to
make that happen we'll both need your feedback and your help.

I'd like to extend a big thanks to both Alexandre Poirot and Alexandre
Lissy for working on this!

Any information on how to take it for a spin today? Where to file bugs,

[b2g] B2G Release scheduling and tree rules

[Jonas Sicking]

[This is a slightly cropped version of an email that went out on
internal lists. The only thing removed is a few partner-related
dates.]

Hi All,

First off, we've decided to call the next FirefoxOS release
(previously called v1.5) our v2.0 release. Note that this in and of
itself doesn't mean any process changes, it's mainly a naming thing.
There will be a follow-up email discussing the feature set we're
targetting which hopefully will make it clear why we're calling the
release 2.0.

We'll be discussing this schedule on 9am PST gaia meeting on tuesday,
as well  as the coordination meeting 5pm PST meeting also on tuesday.
Feedback there is very much encouraged.

Here's the schedule that we've discussed and cleared internally and
with partners:

Mar 17 - April 28: Stabilization for 1.3T/1.3/1.4
April 29: Official "dev start" for 2.0
April 29 - June 8: 2.0 development
June 9: 2.0 branch date
June 9 - July 21: Stabilization for 2.0
July 22: Official "dev start" for 2.1

Since it's important to understand what these various dates mean,
here's a more detailed explanation:

Mar 17 - April 28: Stabilization for 1.3T/1.3/1.4

This time is intended for fixing any critical bugs that come up. I.e.
bugs that we find during our and partner testing.

If you don't get any 1.3T/1.3/1.4 bugs assigned to you in this time
period, please do start on 2.0 work. This can either be new features,
or working on the "top 25" backlog items of technical debt. It's up to
each team to do the tradeoff between technical debt, polish and
creating a product that's joyful to use vs. adding new features.

However since we know that we will be finding plenty of 1.3T/1.3/1.4
issues, keeping this time scheduled for those releases allows us to
keep a more realistic schedule.

April 29: Official "dev start" for 2.0

This date mostly exists to help our planning. No actual rule changes
happening on this date. The rules both before and after April 29th is
that 1.3/1.4 bugfixing is highest priority, and 2.0 development comes
after that.

This date also works as a useful checkpoint. If your team still has a
long list of blockers for 1.3T/1.3/1.4 then we should immediately
reasses if we should move some of the 2.0 targetted features to a
later release.

The flip side of this is of course that we need to get better at
finding bugs earlier. Bugs that we don't find until after this date is
problematic. We're working with QA and partners to try to get bugs to
developers earlier.

April 29 - June 8: 2.0 development

Development happens on m-c and gaia-master.

Throughout this we should aim to have a policy of "no known
regressions". I.e. if a patch to implement a new feature lands, but
the feature is buggy or it breaks other things, then it should be
immediately backed out or disabled.

The goal is that by the end of this period the 2.0 development should
be done. I.e. it's not enough to have landed enough patches to get the
feature mostly working. We should aim to always keep m-c/gaia-master
to be of release quality as best we can. Whenever something isn't
working quite as it should, it slows down other developers.

When landing big new features, please consider landing them turned off
by default until they have gotten wider testing and are of sufficient
quality to be turned on.

This also means that you'll want to have your initial feature landings
happening a week or two before June 8 so that any followup work can be
done before June 8th.

If you have a big new feature or refactoring patch that's ready just a
few days before June 8th, consider waiting to land it, or waiting to
turn it on, until after June 8th so that it goes into the next release
instead. It's better to make big changes early in the next release,
than late in this one.

June 9: 2.0 branch date

Gaia 2.0 branch created. Mozilla-central goes to aurora branch.
Actual branching happens sometime during the 9th pacific timezone, so
if you want to make sure to have your patches in the 2.0 release it
needs to land on the 8th or before that.
Joint triages begin.
Soft String freeze, try to get all strings landed before this date.
Anything beyond this should have the "late-l10n" keyword.

Beyond this date we will be restrictive about what gets uplifted to
the 2.0 release. So don't count on your patches getting uplifted if
it's not for a blocker. This applies both to gaia and gecko patches.

June 9 - July 21: Stabilization for 2.0

The top priority is to help out with the 2.0 release. That doesn't
just include bugs that for sure are in your code. It also includes
helping out with understanding bugs that we don't know what they are
caused by. And of course if you can spend time on helping other teams
that are overwhelmed with blockers, then that will help the project a
lot.

However if you don't have any blockers, and you can't effectively help
if you don't have any critical bug work to do, then feel free to start
on 2.1 development, or do code maintenance, or write more tests.

July 22: Official "de

[b2g] ZTE Open - Twitter crashing / slow sometimes slow to respond

[markkadamplant]

Hi,

Using a ZTE Open from the Ebay UK store - phone came wih 
OPEN_EU_DEV_FOS_V1.0.0B02 and I haven't upgraded or rooted the phone

Has anyone else experienced issues with twitter? Crashes almost every time I 
use it,

And sometimes the phone is slow to respond - while I know the phone isnt using 
lightning fast specs - I wondered if this is the software and updates fix this?

Thanks,

Mark

Re: [b2g] Introducing Mulet

[Kartikaya Gupta]

Cool! Are there any technical docs on this? In particular I'm interested 
to know if it uses the gonk widget backend and APZC code. I have a patch 
that might potentially be breaking input in Mulet, depending on what 
it's doing.


Cheers,

Alexandre Poirot and Alexandre Lissy have been working hard on a new
development environment that should be a big improvement over both
what we use internally for Gaia development, and what we are asking
3rd party app developers to use when developing apps for FirefoxOS.

The basic idea behind this environment is to take Firefox Desktop as
it exists today (including its support for both internal and external
dev tools) and then run it using the same Gecko that we use for
FirefoxOS. So the backend half is FirefoxOS, the frontend part is
Firefox desktop.

This means that we'll have the exact same great development experience
that we have for Firefox desktop today, but we can use the real
implementation of various FirefoxOS specific APIs that we use on
devices.

One nice example of this is that we can keep the app: protocol working
in Mulet. So we don't need to rely on running a local http server and
run gaia through special http urls. Ultimately the goal is to enable
the app: protocol in Mulet to either load from a compressed zip file,
or directly from your gaia source tree.

Once Mulet is ready, it will *replace* the following development environments:
* B2G Desktop
* Gaia-on-Firefox-desktop
* Simulator

So it will be one tool that is usable for gaia developers, gecko
developers and 3rd party app developers.

The name "simulator" might still be around since it's something that
we've been evangelizing to developers a lot. But it will eventually be
based on Mulet.

The goal is to make this tool have nightly releases which works just
like firefox desktop. Or you will be able to build it yourself if you
need to depend on tip. This will require the help of the releng team
though.

Making all of this play well together is a lot of work. So any help
you can provide to Alexandre and Alexandre is very appreciated. We
want this environment to fit your needs, so we can build in whatever
features or tools that will make development better for you. But to
make that happen we'll both need your feedback and your help.

I'd like to extend a big thanks to both Alexandre Poirot and Alexandre
Lissy for working on this!

/ Jonas

No, it's a desktop build, so it's using the linux/mac/windows widgetry.

Re: [b2g] question regarding realtime performance guarantees

Thanks for the replies
